What is the primary purpose of pre-transfusion testing?
To conduct genetic testing
To administer plasma derived medicinal products
To identify potential blood donors
To ensure compatibility and prevent immune-mediated hemolytic reactions
What is the significance of performing a direct antiglobulin test (DAT) in pre-transfusion testing?
To determine ABO blood group
To detect antibodies bound to red blood cells
To assess platelet count
To measure hemoglobin levels
Why is it important to verify patient identification before collecting a pretransfusion specimen?
To ensure the patient has insurance coverage
To confirm the patient's blood type

How does the presence of alloantibodies impact pre-transfusion testing?
It does not affect the testing process
It may lead to incompatible blood transfusions
It increases the shelf life of blood components due to preservative effects of antibodies
It reduces the risk of immune-mediated hemolytic reactions
